$1$ D可压缩到不可压缩极限的唯一性

Uniqueness of the $1$D Compressible to Incompressible Limit

Rinaldo M. Colombo, Graziano Guerra

摘要:

在等熵近似下,考虑一维两种不可混溶的可压缩流体。第一流体被第二流体包围并与第二流体接触。当第一流体的马赫数为零时,两种流体的耦合动力学结果为可压缩到不可压缩极限,并且已知满足ODE-PDE系统。下面提供了该极限的特征,以确保其唯一性。

英文摘要:

Consider two compressible immiscible fluids in 1D in the isentropic approximation. The first fluid is surrounded and in contact with the second one. As the Mach number of the first fluid vanishes, the coupled dynamics of the two fluids results as the compressible to incompressible limit and is known to satisfy an ODE--PDE system. Below, a characterization of this limit is provided, ensuring its uniqueness.
